Description

Technical Field

[0001] This utility model relates to the field of processing tooling technology, specifically to a high-efficiency processing tooling for aluminum alloy doors and windows. Background Technology

[0002] Aluminum alloy door and window processing fixtures refer to specialized equipment or tools used to improve the production efficiency, processing accuracy, and product quality of aluminum alloy doors and windows. Their core purpose is to optimize various processing steps during production, including cutting, punching, milling, and assembly.

[0003] In aluminum alloy door and window processing, three-jaw clamps are commonly used tools to stabilize workpieces and ensure stability during processing. However, novice operators often cause problems by applying excessive force due to insufficient understanding of equipment characteristics and workpiece material properties. Aluminum alloy is a material with moderate strength and low hardness, and its compressive strength is relatively weak. If excessive clamping force is applied during clamping, it can cause localized deformation of the profile. This deformation may affect the accuracy of subsequent processing and product quality, and in severe cases, may prevent the workpiece from returning to its original shape. From a materials mechanics perspective, aluminum alloy will undergo elastic deformation under stress. When the clamping force exceeds its yield strength (usually 150-350 MPa), the profile will undergo permanent deformation, meaning that even after releasing the clamp, the workpiece cannot return to its original shape. In this case, the dimensional accuracy and appearance quality after processing will fail to meet requirements, thus causing irreversible damage to the product.

[0004] In view of this, we propose a high-efficiency processing fixture for aluminum alloy doors and windows. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency processing fixture for aluminum alloy doors and windows. This high-efficiency processing fixture for aluminum alloy doors and windows solves the problem that when beginners use a three-jaw chuck, the excessive clamping force can easily lead to deformation of the profiles and affect product quality, and in severe cases, cause irreversible damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency processing fixture for aluminum alloy doors and windows includes a machine body, an electric rotating head mounted on the machine body, and a clamping mechanism mounted on the machine body. The clamping mechanism includes: an air inlet, a connecting rod, an outer ring, an inner ring, a hollow column, a pressing column, a pressing block, a telescopic pressing component, and a fixed pressing component. An overpressure mechanism is provided on the air inlet, and the overpressure mechanism includes: An exhaust pipe is fixedly connected to the outer wall of the air inlet. A through ring is fixedly connected to the inner wall of the exhaust pipe. A fixed disc is fixedly connected to the inner wall of the exhaust pipe. One end of a return spring is fixedly connected to the outer wall of the fixed disc. The other end of the return spring is fixedly connected to a blocking disc. A guide rod is fixedly connected to the outer wall of the blocking disc. The outer wall of the guide rod is slidably connected to the inner wall of the fixed disc.

[0007] Preferably, an outer ring is fixedly connected to the outer wall of the air inlet, the outer wall of the outer ring is rotatably connected to the inner wall of the inner ring, one end of a connecting rod is fixedly connected to the outer wall of the outer ring, the other end of the connecting rod is fixedly connected to the outer wall of the body, a hollow column is fixedly connected to the outer wall of the inner ring, a pressing column is elastically connected to the inner wall of the hollow column by a spring, and a pressing block is fixedly connected to the outer wall of the pressing column.

[0008] Preferably, the inner wall of the outer ring is connected to the inner wall of the inner ring, and the inner wall of the outer ring is connected to the inner wall of the air inlet.

[0009] Preferably, the inner wall of the hollow column is connected to the outer wall piston of the pressing column, and the inner wall of the hollow column is in communication with the inner wall of the inner ring.

[0010] Preferably, the inner wall of the pressing block is elastically connected to a telescopic pressing member by a spring, the outer wall of the telescopic pressing member is slidably connected to the inner wall of the pressing block, and fixed pressing members are fixedly connected to both sides of the pressing block.

[0011] Preferably, the inner wall of the exhaust pipe is connected to the inner wall of the air inlet, and the return spring is used to drive the blocking disc to press against the through ring.

[0012] Preferably, the guide rod is used to drive the blocking disc to slide back and forth stably, and a handle is provided on the outer wall of the guide rod for easy manual pulling of the guide rod.

[0013] By employing the above technical solution, this utility model provides a high-efficiency processing fixture for aluminum alloy doors and windows. It possesses at least the following beneficial effects: 1. This utility model incorporates an overpressure mechanism. When the fixed pressing part comes into contact with the workpiece, the resistance increases, and the high-pressure air inside the hollow column also increases further. At this time, the increased high pressure contacts the blocking disc, causing the blocking disc to squeeze the return spring, allowing the excess high-pressure air to pass through the ring and be released. This prevents excessive pressure from damaging the system or generating excessive clamping force on the workpiece, and avoids excessive pressure that may be generated due to over-clamping when operated by novices.

[0014] 2. This utility model incorporates a clamping mechanism that places the aluminum alloy door and window material to be processed between three pressing blocks. An air compressor is connected to the air inlet, allowing high-pressure air to be input. This high-pressure air then passes through the outer ring, inner ring, and hollow column. The high-pressure air compresses the pressing column within the hollow column, causing it to move the pressing blocks, telescopic pressing components, and fixed pressing components toward the workpiece until the telescopic pressing component is compressed. The cylinder on the telescopic pressing component is rotatable, allowing the workpiece to rotate freely when it contacts the workpiece, preventing scratches caused by workpiece displacement during hard contact. The cylinder on the fixed pressing component cannot rotate, thus positioning and clamping the workpiece. The rotatable cylinder on the telescopic pressing component moves freely with the workpiece surface during pressing, effectively preventing scratches caused by hard contact and protecting the appearance quality of the aluminum alloy profile. At the same time, high-pressure air drives the pressing column and pressing block to move synchronously, so that the fixed pressing parts on the pressing blocks in three directions can apply a more uniform clamping force, thereby improving the stability and accuracy of clamping.

An overpressure mechanism 3 is provided on the air inlet 21. The overpressure mechanism 3 includes: an exhaust pipe 31, which is fixedly connected to the outer wall of the air inlet 21. A through ring 32 is fixedly connected to the inner wall of the exhaust pipe 31. A fixed disc 33 is fixedly connected to the inner wall of the exhaust pipe 31. One end of a return spring 34 is fixedly connected to the outer wall of the fixed disc 33. The other end of the return spring 34 is fixedly connected to a blocking disc 35. A guide rod 36 is fixedly connected to the outer wall of the blocking disc 35. The outer wall of the guide rod 36 is slidably connected to the inner wall of the fixed disc 33.

[0019] An outer ring 23 is fixedly connected to the outer wall of the air inlet 21. The outer wall of the outer ring 23 is rotatably connected to the inner wall of the inner ring 24. One end of a connecting rod 22 is fixedly connected to the outer wall of the outer ring 23. The other end of the connecting rod 22 is fixedly connected to the outer wall of the body 1. A hollow column 25 is fixedly connected to the outer wall of the inner ring 24. A pressing column 26 is elastically connected to the inner wall of the hollow column 25 by a spring. A pressing block 27 is fixedly connected to the outer wall of the pressing column 26.

[0020] The inner wall of the outer ring 23 is connected to the inner wall of the inner ring 24, and the inner wall of the outer ring 23 is connected to the inner wall of the air inlet 21. The inner wall of the hollow column 25 is connected to the piston of the outer wall of the pressing column 26. The inner wall of the hollow column 25 is connected to the inner wall of the inner ring 24. The inner wall of the pressing block 27 is elastically connected to the telescopic pressing member 28 by a spring. The outer wall of the telescopic pressing member 28 is slidably connected to the inner wall of the pressing block 27. Fixed pressing members 29 are fixedly connected to both sides of the pressing block 27. The inner wall of the exhaust pipe 31 is connected to the inner wall of the air inlet 21. The return spring 34 is used to drive the blocking disc 35 to press the through ring 32. The guide rod 36 is used to drive the blocking disc 35 to slide back and forth stably. A handle is provided on the outer wall of the guide rod 36 for easy hand pulling of the guide rod 36.

[0021] In use, the high-efficiency processing fixture for aluminum alloy doors and windows of this utility model places the raw material workpiece to be processed between three pressing blocks 27. The air inlet 21 is connected to an air compressor, and high-pressure air is input through the air inlet 21. Then, through the outer ring 23, inner ring 24, and hollow column 25, the high-pressure air compresses the pressing column 26 in the hollow column 25. This causes the pressing column 26 to drive the pressing blocks 27, telescopic pressing parts 28, and fixed pressing parts 29 to move towards the workpiece until the telescopic pressing parts 28 are compressed. The cylinder on the telescopic pressing parts 28 can rotate, so when the telescopic pressing parts 28 come into contact with the workpiece, the workpiece can rotate freely, avoiding scratches caused by workpiece displacement during hard contact. The cylinder on the fixed pressing parts 29 cannot rotate, and the fixed pressing parts 29 position and clamp the workpiece. The rotatable cylinder on the telescopic pressing parts 28 can move freely with the surface of the workpiece when pressing it, effectively avoiding scratches caused by hard contact and protecting the appearance quality of the aluminum alloy profile. At the same time, high-pressure air drives the pressing column 26 and the pressing block 27 to move synchronously, so that the fixed pressing member 29 on the pressing block 27 in three directions can apply a more uniform clamping force, thereby improving the stability and accuracy of clamping.

[0022] At this time, the fixed pressing part 29 is in contact with the workpiece, and the resistance it receives increases. The high pressure air in the hollow column 25 also increases further. The increased high pressure then contacts the blocking disc 35, causing the blocking disc 35 to squeeze the return spring 34. This allows the excess high pressure air to pass through the through ring 32 and be released, thus preventing excessive pressure from damaging the system or generating excessive clamping force on the workpiece. This also avoids excessive pressure that may be generated by over-clamping when operating by a novice.
